Normals not working?
It can happen somethimes that the tool to correct the normals (Ctrl+N, normals_make_consistent)  puts all the normal inside. It is usually linked to a bad topology. 

A quick way to fix that is to flip all the normals (they are consistent, but all in the wrong direction). 

To do that


go to edit mode
select all vertices
press space and search for "Flip normals" Or hit ctrl+f and chose Flip Normals
